Frequently Asked Questions
Are stainless steel tumblers safe for kids at the pool?
Yes. Food-grade 18/8 stainless steel is corrosion-resistant and does not leach chemicals. It's a good poolside choice because it resists rust better than low-grade metals and holds up to drops. Check that lids and valves are BPA-free and silicone parts are soft and removable for cleaning.
How do I keep a straw tumbler from getting moldy after pool use?
Rinse and disassemble the lid and straw after each use, then run the straw and nozzle through a straw brush. Leave parts to air-dry completely before reassembly; for silicone pieces, wipe thoroughly and consider occasional boiling or a dishwasher cycle if the manufacturer allows it.
Which lid style is best to prevent leaks in a pool bag?
Screw-top lids with a thick sealing ring or seal-zone technology tend to resist leaks best. Push-button and flip lids can be convenient but inspect for a positive lock or secondary closure. Also, test any new tumbler on its side with water before tossing it in a bag to confirm real-world leak performance.
